Existing outdoor display products typically have a screen size of 500*500mm, composed of four modules, each measuring 250*250mm. During assembly, the multiple modules are arranged in a grid pattern, requiring differentiation between left and right positions, making the assembly process complex. Utility Model Content

[0003] In view of this, this application provides a display screen that does not require distinguishing between left and right directions during assembly, and the assembly process is simple.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A display screen includes a support bracket and a plurality of display modules. The display modules are arranged in a strip shape and are assembled on the support bracket and arranged along the width direction of the display modules, so that the splicing seam formed between two adjacent display modules extends in the horizontal direction.

[0006] The display module includes a strip-shaped bracket, multiple light panels connected to the same side of the bracket, and an adapter plate connected to the bracket. The multiple light panels are arranged along the length of the bracket and are all connected to the adapter plate.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] like Figures 1-11 As shown, this application embodiment provides a display screen, including a support bracket 20 and display modules 10. Multiple display modules 10 are provided and sequentially assembled on the support bracket 20. Specifically, the support bracket 20 has multiple mounting positions, and the multiple display modules 10 are mounted one-to-one on the multiple mounting positions and fixed with screws. Here, the number of display modules 10 can be three, four, or five.

[0032] The display module 10 is configured as a strip, and multiple display modules 10 are arranged along the width direction of the display module 10. For example, there are four display modules 10. The length of the display surface formed by assembling four display modules 10 is the length of a single display module 10, and the width of the display surface is the sum of the widths of the four display modules.

[0033] With this configuration, multiple display modules 10 can be spliced ​​together in the same direction without needing to distinguish between the left and right directions of the display modules 10, which helps improve assembly efficiency. Moreover, multiple display modules 10 can be arranged vertically, with only a splicing seam between two adjacent display modules 10. This splicing seam extends horizontally, and there are no vertical bright or dark lines on the display surface formed by multiple display modules 10, which helps improve the user's visual experience.

[0034] It should be noted that, according to ergonomic research, the human eye's field of vision is a rectangle with a length-to-width ratio of 16:9. This means that vertical seams are more noticeable and easier for the eyes to perceive than horizontal seams. This solution can improve the user's visual experience by eliminating vertical bright and dark lines on the display surface.

[0035] In the specific design, the length of the display module 10 is set to 480-520 mm, and the width is set to 100-150 mm. Preferably, the display module 10 is a strip structure of 500*125 square millimeters. This allows the display module 10 to be used in a 500*500 square millimeter display. Alternatively, as the stroke of the processing equipment increases, the display module 10 can also be made into a strip structure of 1000*125 square millimeters for use in a 1000*1000 square millimeter display. During the assembly process, there is no need to distinguish between left and right, facilitating assembly.

[0036] Understandably, the substrate in display module 10 is cut from a single motherboard. Compared to a square structure of 250*250 square millimeters, this motherboard can cut more strip structures of 500*125 square millimeters, resulting in less waste material. Therefore, the substrate utilization rate of display module 10 in this solution is higher and the cost is lower.

[0037] In this design, the display module 10 includes a bracket 1 and a light panel 2. The bracket 1 is a strip-shaped structure used to support the light panels 2, and its length and width are the same as the length and width of the display module 10. Multiple light panels 2 are provided, all connected to the same side of the bracket 1, for displaying images. The number of light panels 2 can be two or three. Arranging multiple light panels 2 sequentially along the length of the bracket 1 reduces the length of a single light panel 2, which is beneficial for processing the light panels 2, improves substrate utilization, and saves costs.

[0038] Furthermore, the bracket 1 is equipped with an adapter plate 3 for connecting the power supply and signal from the support bracket 20 to the lamp panel 2. For example, the adapter plate 3 is positioned between the bracket 1 and the lamp panel 2, with the lamp panel 2 covering the adapter plate 3. Multiple lamp panels are provided, all connected to the adapter plate 3, enabling power supply and signal transmission for multiple lamp panels. Similarly, the support bracket 20 has multiple electrical interfaces 50, the number of which matches the number of display modules 10. When multiple display modules 10 are assembled on the support bracket 20, each electrical interface 50 is connected one-to-one to the adapter plate 3 of each display module 10. The multiple electrical interfaces 50 on the support bracket 20 are aligned on the same straight line. During assembly, multiple display modules 10 are sequentially connected to the multiple electrical interfaces 50 via the adapter plate 3, thereby distributing the power supply and signal from the support bracket 20 to the multiple display modules 10 and the multiple lamp panels 2 on each display module 10. This simple connection structure eliminates the need to distinguish between left and right during assembly, improving assembly efficiency.

[0039] In the specific design, the arrangement direction of the multiple electrical interfaces 50 is perpendicular to the length direction of the display module 10, that is, the arrangement direction of the multiple electrical interfaces 50 is consistent with the arrangement direction of the multiple display modules 10. In this way, the multiple electrical interfaces 50 correspond to the same position on the display module 10, and the position of the adapter plate 3 on the multiple display modules 10 can be kept consistent. When preparing materials, the specifications of the display modules 10 are consistent, and there is no need to distinguish the top and bottom order during assembly. The multiple display modules 10 can be interchanged with each other, which is convenient for assembly and has high processing efficiency.

[0040] In some preferred embodiments, multiple electrical interfaces 50 are located on the centerline of the support bracket 20 to make the left and right structures of the support bracket 20 symmetrical, which helps to improve the balance and stability of the support bracket 20. Correspondingly, the adapter plate 3 is also set in the middle of the bracket 1 to make the left and right structures of the display module 10 symmetrical, which helps to improve the balance and stability of the display module 10, and thus improves the balance and stability of the display screen.

[0041] The support bracket 20 has an electrical box 30, which contains circuitry for receiving power and signals, enabling the display modules 10 to display based on the received signals. The electrical box 30 extends along the arrangement direction of the multiple display modules 10, that is, it extends along the width direction of the display modules 10 and connects multiple display modules 10 simultaneously. Since the multiple display modules 10 are arranged in the same direction, only one electrical box 30 is needed to connect the multiple display modules 10, and the electrical box 30 can be located in the middle of the support bracket 20, which helps improve the structural balance.

[0042] In this scheme, the distance between two adjacent pixels located on two adjacent light panels 2 is m. These two pixels represent the center-to-center distance between two light-emitting chips located on either side of the seam between the two adjacent light panels 2. m is the pixel spacing at the seam of the two adjacent light panels 2. The distance between two adjacent pixels located on the same light panel 2 is n. These two pixels represent the center-to-center distance between two adjacent light-emitting chips located on the same light panel 2. n is the pixel spacing on the light panel 2. The two pixels m and n satisfy -3% ≤ (mn) / n ≤ 3%, meaning the difference between m and n is less than or equal to 3% of the value of n, so that the values ​​of m and n are close.

[0043] In the specific design, when the spacing n = 1.95 between two adjacent pixels on the same light board 2 (i.e., when the pixel spacing on light board 2 is set to 1.95), the spacing m between two adjacent pixels on two separate light boards is m = 1.95 ± 1.95 * 3%, meaning the value of m ranges from 1.8915 to 2.0085 millimeters. This ensures that no bright or dark lines are generated at the seam between two adjacent light boards.

[0044] Bright and dark lines on the screen are caused by minute errors in pixel pitch. For example, if the spacing between the LEDs at the splicing seam is too large, the brightness will decrease, resulting in dark lines; conversely, if the spacing is too small, the brightness will increase, resulting in bright lines. By controlling the difference between m and n to within 3%, bright and dark lines can be eliminated at the splicing seam on the display module 10, resulting in better display quality and an improved user experience.

[0045] During processing, the position of the light-emitting chips on the lamp board 2 can be adjusted, as can the spacing between two adjacent lamp boards 2, to ensure that the point spacing at the splicing seam of two adjacent lamp boards 2 meets the aforementioned requirements. For example, during processing, a specialized jig can be used to splice multiple lamp boards 2 onto the same bracket 1, which can effectively control the gap between the splicing seams of two adjacent lamp boards 2. After assembly, the splicing seams are checked for bright or dark lines. If bright or dark lines are found, the process is repeated, thus ensuring that the produced display module 10 is free of bright or dark lines. In this way, when multiple display modules 10 are assembled onto the support bracket 20, no bright or dark lines will be generated between two adjacent lamp boards 2 on the display module 10; only the splicing seam between two adjacent display modules 10 will be visible due to assembly errors.

[0046] Specifically, two light panels 2 are provided and arranged along the length of the light panel 2. For example, a single light panel 2 is set to 250*125 square millimeters. In this way, the aspect ratio of the display module can be larger, thereby solving the problem of vertical bright and dark lines on larger-sized displays.

[0047] It should be noted that, due to the limitations of the processing equipment's stroke and the problem that the larger the size, the greater the precision error, assembling multiple light panels 2 on a bracket 1 can improve the yield rate and reduce the processing difficulty.

[0048] In some embodiments, the adapter board 3 has opposing first and second sides. The first side of the adapter board 3 is close to the bracket 1, and the second side of the adapter board is close to the lamp board 2. The first side of the adapter board 3 is provided with a main interface 34, and the second side of the adapter board 3 is provided with multiple sub-interfaces. Due to the circuit structure on the adapter board 3, the main interface 34 is connected to the multiple sub-interfaces. The main interface 34 is plugged into an external structure, and the multiple sub-interfaces are connected to multiple lamp boards 2 respectively. In this way, the adapter board 3 can realize the conversion of power and signals, thereby enabling the multiple lamp boards 2 to display according to the signals input to the electrical box.

[0049] In the specific design, the adapter board 3 has multiple interfaces, including signal interfaces and power supply interfaces. The number of signal interfaces and power supply interfaces can be set to one and connect simultaneously to multiple lamp boards 2, or multiple interfaces can be set and connected one-to-one to multiple lamp boards 2. Each lamp board 2 is connected to at least one signal interface and one power supply interface to achieve its own power supply and signal transmission.

[0050] In some embodiments, when the adapter plate 3 is connected to the bracket 1, the main interface 34 on the adapter plate 3 protrudes from the bracket 1 in a direction away from the lamp plate 2. When multiple display modules are assembled on the support bracket, they can be plugged into the electrical interface 50 on the support bracket through the main interface 34, which is beneficial for positioning the display modules and for a more stable and reliable connection.

[0051] The bracket 1 has a waterproof structure on the side away from the light panel 2, surrounding the main interface 34. A waterproof groove 40 is provided on the support bracket 20 near the display module 10, and the electrical interface 50 is located within the waterproof groove 40. When the main interface 34 of the adapter board 3 is plugged into the electrical interface 50, the waterproof structure also plugs into the waterproof groove 40. This plugging and engagement of the waterproof structure and the waterproof groove 40 achieves waterproofing for both the electrical interface 50 and the main interface 34. Thus, the waterproof structure enhances the stability and reliability of the connection between the display module and the electrical interface 50.

[0052] In some preferred embodiments, the waterproof structure includes an annular protrusion 12 and a waterproof rubber ring 4. The annular protrusion 12 is disposed on the bracket 1 and surrounds the outer periphery of the main interface 34. Specifically, the annular protrusion 12 and the bracket 1 are integrally formed. The waterproof rubber ring 4 is fitted around the outer periphery of the annular protrusion 12, and the outer wall of the waterproof rubber ring 4 is provided with waterproof texture. When the electrical interface 50 is inserted into the main interface 34 of the adapter plate 3, the outer wall of the waterproof rubber ring 4 abuts against the inner wall of the waterproof groove 40. Due to the waterproof texture design on the waterproof rubber ring 4, the waterproof sealing performance between the waterproof rubber ring 4 and the waterproof groove 40 can be better improved.

[0053] The waterproof structure also includes a latch 5, which engages with the inner side of the annular protrusion 12 and limits the waterproof rubber ring 4 to the outer periphery of the annular protrusion 12. This design of the latch 5 prevents the waterproof rubber ring 4 from detaching from the annular protrusion 12, facilitating repeated insertion and removal of the display module and electrical box. For example, the latch 5 has an outer edge; when the latch 5 engages with the annular protrusion 12, the outer edge of the latch 5 abuts against the waterproof rubber ring 4, so that the waterproof rubber ring 4 abuts between the bracket 1 and the outer edge of the latch 5.

[0054] In addition, the waterproof rubber ring 4 can also be fixed to the outer periphery of the annular protrusion 12 by adhesive or heat fusion.

[0055] like Figure 5 As shown, the annular protrusion 12 has an annular groove on its end face away from the bracket 1. The waterproof rubber ring 4 has an inner edge, which is embedded in the annular groove. When the latch 5 engages with the annular protrusion 12, the outer edge of the latch 5 abuts against the inner edge of the waterproof rubber ring 4, pressing the inner edge of the waterproof rubber ring 4 tightly within the annular groove. In this way, the latch 5 presses the waterproof rubber ring 4 firmly onto the annular protrusion 12, which helps improve the installation stability of the waterproof rubber ring 4.

[0056] To achieve internal waterproofing of the display module 10, a potting groove is provided on the side of the bracket 1 near the lamp board 2. The potting groove contains an adapter plate 3 and sealant, with the sealant covering and sealing the adapter plate 3 within the groove. Here, the adapter plate 3 is fixed to the bracket 1 with screws, and being exposed to external air, it is susceptible to water ingress and corrosion damage. This solution, by using potting sealant to seal the adapter plate 3 within the potting groove, prevents the adapter plate 3 from contacting external air, thus extending its service life and improving structural stability and reliability. Furthermore, because the adapter plate 3 is covered with sealant, the circuitry and components on it have good sealing and waterproofing properties. Even if the display module's outer casing becomes loose or damaged, external moisture entering the structure will not corrode the interfaces on the adapter plate 3, further extending the lifespan of the display module.

[0057] In some embodiments, the back side of the light panel 2 is coated with a waterproof coating. This waterproof coating covers the components of the light panel 2, thereby achieving waterproofing of the light panel 2 itself, which is beneficial for outdoor use. Alternatively, a waterproof coating can also be applied to the edges of the light panel 2, meaning the waterproof coating simultaneously covers both the back side and the edges of the light panel 2, further enhancing the waterproof effect. Here, the waterproof coating can be a UV conformal adhesive.

[0058] like Figure 4 As shown, the bracket 1 has multiple perforated holes 11, which are evenly distributed and penetrate the bracket 1 to expose the waterproof coating on the lamp panel 2, thereby improving the heat dissipation of the lamp panel 2. For example, the perforated holes 11 can be strip-shaped and extend along the length of the bracket 1; specifically, there are 16 perforated holes 11. Since the lamp panel 2 itself is waterproof, there is no need for the bracket 1 and lamp panel 2 to work together for waterproofing; the bracket 1 only serves to support and protect the lamp panel 2. In this way, by setting perforated holes 11 on the bracket 1, the heat inside the lamp panel 2 and the bracket 1 can be directly convectioned to the outside, improving the heat dissipation effect and waterproof reliability. At the same time, it can also reduce equipment investment costs and shorten the development cycle of manufacturing processes, and the overall weight of the display module is lighter, making it easier to install and transport.

[0059] A pull ring 13 is provided on the side of the bracket 1 away from the light panel 2. When handling and installing the display module, the pull ring 13 can drive the bracket 1 to move, which is beneficial for position calibration, improving the accuracy of assembly and reducing the difficulty of work.

[0060] like Figure 4-7As shown, in the first embodiment, the signal interface on the adapter board 3 is equipped with a first wireless module 31, and the lamp board 2 is equipped with a second wireless module 21. The first wireless module 31 and the second wireless module 21 are communicatively connected to enable communication between the lamp board 2 and the signal interface. Specifically, the first wireless module 31 and the second wireless module 21 are positioned opposite each other, and when the lamp board 2 is connected to the bracket 1, the first wireless module 31 and the second wireless module 21 are positioned close together. This wireless connection for signal transmission simplifies the assembly process, reduces the amount of wiring used, and saves costs.

[0061] like Figure 6 , 7 As shown, the power supply interface is provided with an elastic conductive element 32 and an annular seal 33. The annular seal 33 is arranged around the outer periphery of the elastic conductive element 32. The lamp board 2 is provided with a conductive sheet 22, and the conductive sheet 22 and the elastic conductive element 32 are positioned opposite each other. When the lamp board 2 is connected to the bracket 1, the elastic conductive element 32 abuts against the conductive sheet 22 to realize the electrical connection between the lamp board 2 and the power supply interface. At the same time, the annular seal 33 abuts against the lamp board 2 and surrounds the outer periphery of the conductive sheet 22. In this way, the annular seal 33 abuts between the lamp board 2 and the bracket 1, which can seal the inner elastic conductive element 32 and the conductive sheet 22, which is beneficial to improving the safety and stability of the power supply connection.

[0062] Specifically, the elastic conductive element 32 is set as a spring seat, the annular sealing element 33 is set as a sealing sleeve, and the conductive sheet 22 is set as a copper sheet. The structure is simple and easy to process.

[0063] It should be noted that, in the combination of sealant and waterproof coating, the first wireless module 31 is mounted on the adapter plate 3, and the sealant covers and seals both the first wireless module 31 and the adapter plate 3. The second wireless module 21 is mounted on the back side of the lamp board 2, and the waterproof coating covers both the second wireless module 21 and the back side of the lamp board 2. Since the elastic conductive element 32 needs to contact the conductive sheet 22, under the action of the annular sealant 33, the sealant does not cover the elastic conductive element 32, and the waterproof coating does not cover the conductive sheet 22.

[0064] like Figure 8-11As shown, in the second embodiment, the lamp board 2 and the adapter board 3 are connected by a connecting cable, meaning both the signal interface and the power supply interface are connected to the adapter board 3 via the connecting cable. There can be one connecting cable, which can provide both power and signal transmission; or there can be multiple connecting cables, each providing both power and signal transmission. At least one end of the connecting cable is equipped with a waterproof connector assembly 6, allowing the connecting cable to connect to the lamp board 2 or the adapter board 3. This waterproof connector assembly 6 facilitates the assembly and disassembly of the lamp board 2 and the adapter board 3 for maintenance; it also improves the waterproof performance of the internal wiring, preventing external moisture from affecting the signal and power transmission on the lamp board 2, thereby giving the display module a longer service life and greater stability.

[0065] In the preferred embodiment, a waterproof connector assembly 6 is provided on the side of the lamp panel 2 near the bracket 1. The waterproof connector assembly 6 is communicatively connected to the signal interface via a first connecting line 7 and electrically connected to the power supply interface via a second connecting line 8. Multiple configurations exist for the lamp panel 2; here, two lamp panels are used, and two waterproof connector assemblies 6 are also used. The two waterproof connector assemblies 6 are respectively located in the middle area of ​​the two lamp panels 2, and are symmetrically arranged on both sides of the adapter plate 3. This improves the structural balance and stability. The first connecting line 7 and the second connecting line 8 are the connecting lines mentioned above.

[0066] The waterproof connector assembly 6 includes a first connector 61 and a second connector 62. The first connector 61 is disposed on the lamp panel 2. When the first connector 61 and the second connector 62 are inserted, the second connector 62 wraps around the first connector 61 and forms a sealing structure on the outer periphery of the first connector 61. In this way, the sealing and waterproofing between the first connector 61 and the second connector 62 can be achieved through the insertion of the first connector 61 and the second connector 62. The structure is simple and easy to install.

[0067] In a specific embodiment, the sealing structure may include a sealing ring disposed between the outer wall of the first connector 61 and the inner wall of the second connector 62 to seal the connection between the first connector 61 and the second connector 62. The sealing structure may also include a sealing gasket disposed between the end face of the second connector 62 and the lamp panel 2. When the first connector 61 and the second connector 62 are connected, the sealing gasket is clamped between the second connector 62 and the lamp panel 2.

[0068] like Figure 9 As shown, the sealing structure includes a sealing ring 63, which is sleeved on the outer periphery of the first connector 61, and the outer wall of the sealing ring 63 is provided with sealing grooves. When the first connector 61 and the second connector 62 are connected, the sealing ring 63 is clamped between the outer wall of the first connector 61 and the inner wall of the second connector 62.
